At the upper 5 frigerating system comprising a portable unit end of. each of said pipes 12 is an elbow 13 diadapted to be installed in a closed cooling chamrected outwardly from the unit and into the coolher for causing a circulation and cooling of the ing chamber. The pipes 12 are fitted with a air within the chamber by passing currents of series of horizontally arranged screens 14., the air through the unit in contact with cooled brine screens 14 being spaced at selected intervals 10 sprays, accumulating the brine and discharging throughout the length of the pipes 12. it from the unit, and then forcing the air through It will be understood that the spray header 10 air ducts equipped with means for freeing the is supplied with cooled brine liquid under presair from moisture into the cooling chamber. sure through a supply pipe 15 controlled by a The specific advantages of the invention will valve 16.

In the embodiment of the invention illustrated By reference to the drawing, it will be noted in the drawing, the refrigerating unit is shown also that a longitudinal baffle wall 1'7 is positioned as comprising a portable base 1 provided with between the rows of pipes 7 and 12. The bafifle 25 legs or standards 2. Upon the base 1 is mounted extends from the top face of the box 3 to the a longitudinal box 3 constituting an accumulatupper wall 9 of the unit to prevent the crossing chamber for the cooling liquid, which liquid draft of currents of air across the upper end of may be withdrawn from the box through a disthe unit and to force the currents of air entercharge pipe l. A longitudinal baffle wall 5 is ing the unit into the pipes 7. supported by the inner face of the top wall of From the foregoing description, it will be the box 3 and extends downwardly in an inclined understood that the operation of the device is direction, as clearly illustrated in Fig. 2.

The pipes spray and driven downwardly through the pipes 7 enter through openings in the top wall of the and into the box 3. The liquid from the sprays box 3 and extend upwardly therefrom to a point is deflected by the baffle 5 and accumulates in spaced from the ceiling 9 of the cooling chamber, the bottom of the box 3.

A gravity If desired, an additional Wall may be substituted separation of the liquid from the air occurs in for the ceiling and formed as a part of the unit. the box 3 and the air, substantially freed from A transvers p y h d 10 x nd acr moisture, is forced into the pipes 12 and driven 50 the upper ends of the series of pipes '7 and has outwardly into the cooling chamber. The upconnected thereinto a series of nozzles 11, a nozward passage of the air currents through the zle being axially arranged in respect of the upper pipes 12 and through the screens 14 tends to drop end of each of the pipes '7, the discharge ends out any entrained liquid in the outwardly movof the nozzles extending into the upper ends of ing currents of air, so that the air forced from 55 said pipes. the outlet of the pipes 12 is substantially dry.

The forced movement of the air currents outwardly from the pipes 12 causes currents of air to be set up in the cooling chamber, which circulate generally from the upper part of the cooling chamber downwardly toward the floor thereof, thus coming into contact with objects such as meat carcasses suspended in the cooling chamber;

I am aware that the invention may be modified in numerous particulars without departing from the spirit and scope thereof. I do not limit myself, therefore, to the exact construction shown and described, but what I claim and desire to secure by Letters Patent is:-

1. In a refrigerating system, the combination of a portable base, a longitudinally rectangular box supported by said base constituting a liquid accumulating chamber, a longitudinal series of pipes supported by the top wall of said box and extending thereinto, a spray nozzle located in the upper end of each of said pipes, a second series of pipes arranged in a longitudinal series parallel with said first named pipes and supported by the top wall of said box and extending thereinto, a baiile in said base below and preventing spray from entering said second series of pipes, and a longitudinal bafile wall located between said two series of pipes.

2. A refrigerating system comprising a rectangular hollow chamber, a series of pipes supported by and having an outlet opening below the top wall of said chamber, a second series of pipes supported by and having an inlet opening below the top wall of said chamber, a baflie wall in said chamber between and extending downwardly beyond the lower ends of said series of pipes, a spray header positioned across the upper ends of said first series of pipes, nozzles carried by said spray header and extending respectively into the open upper ends of said first series of pipes, and means for supplying cooling liquid to said spray header.

3. A refrigerating system comprising a rectangular hollow chamber, a series of pipes supported by and having an outlet opening below the top wall of said chamber, a second series of pipes supported by and having an inlet opening below the top wall of said chamber, a baffle wall between the lower ends of said series of pipes, a baffle wall arranged within said chamber and extending downwardly from the top wall thereof, the lower end of said bafiie wall terminating in an area below the outlet ends of said first series of pipes, a spray header positioned across the upper ends of said first series of pipes, nozzles carried by said spray header and extending respectively into the open upper ends of said first series of pipes, and means for supplying cooling liquid to said spray header.

4. A refrigerating system comprising a rectangular hollow chamber, a series of pipes supported by and having an outlet opening below the top wall of said chamber, a second series of pipes supported by and having an inlet opening below the top wall of said chamber, a baiiie wall between the lower ends of said series of pipes, a bafiie wall arranged within said chamber and extending downwardly from the top wall thereof, the lower end of said baffie wall terminating in an area below the outlet ends of said first series of pipes, a second baffle wall within said chamber extending upwardly and inwardly from the bottom thereof and terminating below the area of the inlet ends of said second series of pipes, a spray header positioned across the upper ends of said first series of pipes, nozzles carried by said spray header and extending respectively into the open upper ends of said first series of pipes, and means for supplying cooling liquid to said spray header.

5. A refrigerating system comprising a rectangular hollow chamber, a series of pipes supported by and having an outlet opening below the top wall of said chamber, a second series of pipes supported by and having an inlet opening below the top wall of said chamber, a series of reticulated screens located in each of said second named series of pipes, a baiile wall between the lower ends of said series of pipes preventing spray from entering said second series of pipes, a spray header positioned across the upper ends of said first series of pipes, nozzles carried by said spray header and extending respectively into the open upper ends of said first series of pipes, and means for supplying cooling liquid to said spray header.

6. A refrigerating system comprising a rectangular hollow chamber, a series of pipes supported by and having an outlet opening below the top wall of said chamber, a second series of pipes supported by and having an inlet opening below the top wall of said chamber, a series of reticulated screens located in each of said second named series of pipes, an inclined baffie in said chamber for deflecting the liquid from the outlet ends of said second named series of pipes, a baffle wall below the lower ends of said second series of pipes preventing spray from entering said second series of pipes, a spray header positioned across the upper ends of said first series of pipes, nozzles carried by said spray header and extending respectively into the open upper ends of said first series of pipes, and means for supplying cooling liquid to said spray header.
